ActiveGuard™ Mattress Liners have been used to control house dust mites, and they also are commercially available as an integrated pest management tool for use against bed bugs (Cimex lectularius). The aim of our study was to evaluate responses of numerous populations of the bed bug to the permethrin-impregnated fabric, with particular regard to contact toxicity, repellency, and feeding inhibition. Continuous exposure to ActiveGuard fabric resulted in rapid intoxication for three of four populations, with 87 to 100% of moderately pyrethroid-resistant and susceptible bed bugs succumbing by 1 d. In comparison, a highly resistant population reached 22% mortality at 10 d. Video data revealed that bed bugs readily traversed ActiveGuard fabric and spent a considerable amount of time moving about and resting on it during a 12-h period. ActiveGuard fabric was non-repellent to bed bugs from five tested populations. Furthermore, significantly fewer bed bugs successfully fed to repletion through ActiveGuard fabric than through blank fabric for the five populations. With just 30 min of feeding exposure, mortality ranged from 4% to 83%, depending upon the bed bug strain. These laboratory studies indicate that ActiveGuard liners adversely affected bed bugs from diverse populations.
ActiveGuard™床垫衬里已被用于控制屋尘螨，并且它们也作为一种用于对抗臭虫（温带臭虫）的综合害虫管理工具在市场上有售。我们研究的目的是评估大量臭虫种群对氯菊酯浸渍织物的反应，尤其关注接触毒性、驱避性和取食抑制。连续接触ActiveGuard织物导致四个种群中的三个迅速中毒，87%至100%的中度拟除虫菊酯抗性和敏感臭虫在1天内死亡。相比之下，一个高抗性种群在10天时死亡率达到22%。视频数据显示，臭虫很容易穿过ActiveGuard织物，并且在12小时内花费大量时间在上面活动和休息。ActiveGuard织物对五个测试种群的臭虫没有驱避作用。此外，对于这五个种群，成功通过ActiveGuard织物饱食的臭虫明显少于通过空白织物的臭虫。仅经过30分钟的取食暴露，死亡率在4%至83%之间，具体取决于臭虫品系。这些实验室研究表明，ActiveGuard衬里对不同种群的臭虫有不利影响。
